I just made a quick test. Opening the inbox of my test account (IMAP) on 
googlemail.com took quite some time because KMail had to fetch the 
headers of 78458 messages. Afterwards opening this folder repeatedly 
took about 30 seconds (after a restart of KMail). The CPU load went up 
to 50 % (i.e. 100 % on one CPU core) for the better part of those 30 
seconds, so opening such a large folder might be much slower on a less 
powerful system. FWIW, I'm using openSUSE 10.3 x86-64 on an Intel(R) 
Core(TM)2 CPU 6600  @ 2.40GHz.

For comparison: Opening a local maildir folder with 51808 messages with 
KMail 1.9.9 (KDE 3.5.9) took about 15 seconds. So KMail 1.9.9 seems to 
be a bit faster than KMail 1.10.0, but not by far.

As always with such measurements: Your milage might vary.

Ingo
